The NFL has stepped into a growing fight over NFL prediction markets and how they should be regulated in the United States.
In a recent public comment letter to Commodity Futures Trade Commission (CFTC) Chairman Michael Selig, the league urged the federal derivatives regulator to take a tougher stance on sports‑related “event contracts” — the products traded on platforms like Kalshi and Polymarket.
These platforms let people trade on the outcome of real‑world events, including NFL games and even smaller in‑game situations. The contracts often work like simple yes/no bets: you buy a position on whether something will happen, and you profit if you’re right.
The CFTC’s proposal would formally define and review these contracts, but the NFL says the plan still “falls significantly short” of protecting game integrity, preventing insider trading, and keeping fans safe.
What Are NFL Prediction Markets?
Prediction markets are online platforms that list contracts tied to specific events. When those events involve the NFL, they become NFL prediction markets. Traders can buy and sell positions on questions like:
- Will a certain team win a game?
- How many points will a team score in a season?
- Will a team make the playoffs?
Under the CFTC’s proposal, these kinds of broad outcomes — final scores, point spreads, season records — would generally be allowed, as long as they settle using clear, league‑verified data and don’t raise major public‑interest concerns.
Where the debate gets heated is around more granular sports markets, such as individual player props and in‑game micro‑events.
Why the NFL Is Worried
The NFL’s letter makes it clear that the league sees serious risks in how prediction markets interact with its games. Its core concerns fall into a few main areas:
- Game integrity and manipulation.
- Insider trading and confidential information.
- Consumer protection and responsible use.
- Gaps in how contracts are reviewed and policed.
For the NFL, the key question is simple: can fans trust that what they’re watching on Sundays isn’t being influenced by obscure markets that only a few insiders really understand?
The NFL’s Push for Stricter Contract Limits
A major theme of the letter is that some types of sports contracts are easier to manipulate than others. The NFL wants the CFTC to outright ban — not just review — certain high‑risk categories, especially when they involve a single player, a small group of people, or sensitive decisions.
Specific examples include:
- Player props and micro‑bets. Contracts on tiny in‑game moments, like whether a quarterback’s next pass is incomplete or a kicker misses a specific field goal, can hinge on the actions of one person. The league argues these markets are too easy to corrupt because a single player or insider could affect the outcome.
- Officiating decisions. Markets tied to whether a penalty is called, or how referees rule on a close play, place pressure directly on officials. The NFL wants these prohibited because they create incentives to question or influence neutral decision‑makers.
- “Knowable in advance” outcomes. Contracts on events like the first play of a game, specific lineup or roster decisions, or certain coaching choices could be resolved with information known internally before kickoff. That makes them particularly vulnerable to insider trading.
- Injury and sensitive‑topic markets. The proposal already disfavors markets on injuries, youth sports, and physical altercations, but the NFL is pushing for clearer, harder bans to stop trading on painful or private aspects of players’ lives.
In short, the NFL is comfortable with markets on the overall outcome of NFL games, but it wants the CFTC to draw a sharp line around granular, easily manipulated event contracts.
Awards, Honors, and a Potential Loophole
Another issue the NFL raises involves markets on awards and honors, such as Offensive Player of the Year or other performance‑linked titles. The CFTC’s draft rules leave room for certain contests and awards to be treated as non‑gaming “contests,” which could fall outside the stricter event‑contract framework.
The NFL warns that this could become a loophole. If markets on sports awards can be classified as harmless contests, platforms might use that category to dodge sports wagering rules.
The league wants tighter definitions so that any market tied directly to on‑field performance is treated like a sports event contract and subjected to the same integrity and consumer‑protection standards.
Insider Trading and Prohibited Persons
Prediction markets sit at the intersection of trading and sports, and that raises the classic problem of insider information. In its letter, the NFL pushes the CFTC to clearly state that trading on material non‑public information — anything from injury reports to internal coaching plans — is manipulative or deceptive under the Commodity Exchange Act.
To back that up, the NFL recommends several concrete steps:
- A league‑wide prohibited bettors list, covering players, coaches, officials, team staff, and other insiders who should not be allowed to trade on NFL event contracts.
- Formal information‑sharing agreements between prediction markets and sports leagues, so platforms can enforce those restrictions and coordinate investigations.
- Stronger enforcement around suspected insider trading, including when trades cluster around sensitive events like injuries or sudden roster changes.
For the league, relying on platforms to “self‑police” is not enough. It wants rules that force coordination and make insider trading in NFL prediction markets explicitly illegal and easier to punish.
Age Limits and Consumer Protections
On the consumer side, the NFL argues that sports‑linked prediction markets should follow standards similar to regulated sports betting. That includes a higher minimum age and clear tools to help users manage risk.
Key recommendations include:
- Minimum age of 21 for trading sports event contracts, instead of the current 18‑plus model used by platforms like Kalshi and Polymarket.
- A centralized self‑exclusion system, so customers who choose to block themselves from trading are excluded across multiple platforms, not just one.
- Built‑in deposit and loss limits, along with notifications and cooldown periods to reduce the risk of chasing losses.
- A ban on margin trading for sports event contracts, so users can’t borrow heavily to amplify risk.
- Restrictions on advertising, aimed at preventing aggressive marketing to younger or vulnerable audiences.
These changes would bring NFL‑related markets closer to the responsible gambling framework used by state‑regulated sportsbooks, even though prediction markets sit under CFTC oversight instead of traditional gaming commissions.
Stronger Review and Ongoing Oversight
The CFTC proposal creates a more ordered, three‑step process for deciding whether event contracts are contrary to the public interest and should be blocked. The NFL supports tighter scrutiny but argues the agency needs to go further, both before and after contracts go live.
In particular, the league calls for:
- More robust pre‑approval review of new sports contracts, so risky markets can be stopped before they attract volume.
- Clear retroactive review authority, allowing regulators to revisit contracts already trading if new integrity concerns arise.
- A willingness to block high‑volume products even if they might migrate offshore, rather than allowing questionable markets simply because they are popular.
The message is that protecting the integrity of NFL games and the trust of fans should outweigh short‑term trading volume, even when that volume is significant.
The Bigger Picture: Federal vs. State and Other Stakeholders
The NFL’s letter is only one piece of a much larger debate about who should oversee prediction markets and how they differ from traditional gambling.
Several other actors are deeply involved:
State attorneys general. A large group of states, including Ohio, have argued that the CFTC is overstepping its authority when it regulates sports‑related contracts, because those markets look a lot like sports betting, which states usually control.
Other leagues and unions. Professional leagues and players’ associations in various sports have raised similar integrity and consumer‑protection concerns, even as some leagues experiment with partnerships in adjacent areas.
Prediction market platforms and crypto advocates. These stakeholders tend to push for lighter, uniform federal rules that highlight prediction markets’ role in price discovery and hedging rather than gambling.
The CFTC is still reviewing all of these comments as part of its ongoing rulemaking process. Whatever final framework emerges will have major consequences for the future of NFL prediction markets, from simple game‑outcome contracts to more complex, real‑time data‑driven markets.
What It Means for the Future of NFL Markets
For now, the NFL is signaling that it wants prediction markets to look more like tightly regulated sports betting than free‑wheeling online speculation. It is comfortable with contracts that reflect the overall outcome of games but wants strict guardrails around anything that could invite manipulation, exploit insider info, or harm fans.
If the CFTC adopts a tougher rule set, platforms trading NFL event contracts will need to:
- Rebuild product menus around allowed outcomes.
- Implement stronger integrity and compliance systems.
- Align age limits and consumer protections with the standards used by sportsbooks.
If the agency leans toward a more permissive approach, expect the NFL and other leagues to keep pushing for stricter controls and to use their own policies — including prohibited bettors lists and data‑sharing restrictions — to protect their games from the most aggressive forms of speculation.
